Whether you?re setting up multiple computers or doing a full backup, cloning hard drives is a common maintenance task. Don?t bother burning a new boot CD or paying for new software ? you can do it easily with your Ubuntu Live CD.Not only can you do this with your Ubuntu Live CD, you can do it right out of the box ? no additional software needed! The program we?ll use is called dd, and it?s included with pretty much all Linux distributions. dd is a utility used to do low-level copying ? rather than working with files, it works directly on the raw data on a storage device.
